Pupils from a secondary school will attempt to set a world record.

The children at Tanbridge House School, in Farthings Hill, Horsham, are working with radio production company Airforce to create an advert which will use as many voices as possible within 90 seconds.

On Monday John Calvert, managing director of Airforce, will visit the school to talk to pupils about how to make a radio advert.

The pupils will be asked to create their own ideas and ten pupils will be chosen to develop their ideas at a workshop.

Year 8 pupils have been chosen to record the advert.
